We plan to remove the librados clone_range, assert_src_version, and src_cmpxattr operations. These operations were introduced in distant past in order to support an early design of RGW, but are not longer used by anything in the tree, are largely untested, and are difficult to continue to support. These are the only operations that allo a single librados operation to operate on multiple objects. I think it is pretty unlikely that there are any users for these operations, but if you are out there, speak up now! Note that there is a proposed rados extension that adds support for multi-object transactions. These are *much* more powerful than this older capability, which is fragile and hard to use. The proposed extension has a PR that is open for review, but it is still not clear whether this is the design path we want to take (or whether it is worth the cost of complexity in the OSD to support it at all). Any librados API user feedback would be helpful.
